Answer: 3 1/3
Step-by-step explanation:
Turned into mixed numbers: -7/3 + 17/3
Multiply all the numbers by 3: -7 * 3 = -21
17 * 3 = 51
3 * 3 = 9
-21 + 51 = 30
30/9
30/9 = 3 1/3
Velocity * time = distance
40 (miles / hour) * t (hours) = 60 (miles)
Take note how the units work. miles/hour * hours = miles. This is an indication that a formula we picked is correct.
Now, looking at our formula (and neglecting units at this point)
40t = 60
t = 60/40
<span>t = 1.5 hours</span>
I think answer is b that is 10raise to 2
Step-by-step explanation:
Apples cost four times as much as oranges per pound.
If the cost of orange =x
then, cost of apples =4x
But,
the costs of apples =2.80$
So,4x=2.80
⠀
⠀
so,oranges costs for per pound =0.70$
Well, if Tina can make 3 pies in one hour, she have to do 6 pies and she have already 2 so she can have as many pies as Bella, so the answer is 2 hours
